Colin Kaepernick thought he was going to be a Raider, not a 49er.

Everything leading up to the 2011 draft led him to believe that, according to a report by Sports Illustrated.

"Coach [Hue] Jackson told me before the draft that they were going to do everything they could to try to get me. I thought there was a good chance they'd pick me. I never heard anything from the 49ers before the draft after I worked out for them [at Nevada]. I just figured they weren't interested," Kaepernick told SI's Peter King.

According to the report, the Raiders had Kaepernick as the No. 1 rated quarterback on their draft board prior to the 2011 draft, and had plans to trade up to get him. The Raiders affection for Kaepernick was not a well-kept secret.

Both teams worked hard to move up to the beginning of the second round. Both teams contacted New England, owners of the first pick of the second round. But the price was a second and third round pick. Neither team was willing to match that. The Raiders abandoned the thought, but the 49ers moved on to talks with the Broncos, who had the 36th pick. Their asking price was much lower - a fourth and a fifth round pick.

And as they say, the rest is history. Kaepernick became a 49er and led them to the Super Bowl two years after being drafted.

The fact that the Raiders didn't get Kaepernick haunts Jackson to this day.

"I think about it all the time, believe me. No question in my mind we wanted it to happen, and no question I thought it could happen. We wanted the kid in the worst way," Jackson told SI.
